Abstract: A method for displaying a region of interest graphic on an imaging system includes: (a) establishing a communication connection over a network between the imaging system and a remote facility; (b) displaying an image frame, the image frame having a reference point; (c) displaying a region of interest graphic on the image frame at a depth determined relative to the reference point, the region of interest graphic having a bottom width, a top width, a height, and an angle between a projection of a first edge line and a projection of a second edge line; (d) changing the depth of the region of interest; and (e) changing the top width and the angle of the region of interest graphic as a function of the change in depth, while maintaining the height and the bottom width of the region of interest graphic substantially unchanged. At least one of steps (b) through (e) is done remotely over the communication connection.

Abstract: Various features are provided for allowing content providers (typically web site operators) to provide customized, multimedia presentations to end users within web pages. One feature involves a web-based player architecture that provides multiple display screens, each of which may correspond to a different content type (e.g., video, menu, caption, logo, animation, etc.). Another feature involves the use of scripting commands embedded within the video file or other streamed content to control various display attributes of the screens and of the player. These display attributes preferably include the visibility states and positions of the screens, such that a video or other streamed content can switch content items into and out of display and/or move screens to new positions during playing of the streamed content.

Desirably a plurality of parallel centrifugal separators have their inlets connected to the fluid line, and gas outlets connected to a dental vacuum pump. The bottom liquid and particle outlet drains to a particle filter. The filtered water can be reintroduced into the gas flow to the vacuum pump, and the collected particles are disposed of in an environmentally sound manner.

Abstract: A cooking oven comprises a cavity having a separating and insulating plate which can be inserted horizontally in the cavity in order to split it in two sub-cavities. Each sub-cavity has heating elements on its side walls. The oven sub-cavities can be singularly or separately and this increases flexibility in use.

Abstract: A circuit arrangement for monitoring an output load (4) of a digital-to-analog current converter (1). The digital-to-analog converter supplies an analog output current dependent on a digital comparison data word to a first resistor (2) and, if present, to the output load (4) arranged in parallel with the first resistor. In order to provide a continuous monitoring of the output load, a digital first comparator (12) compares the data words applied to the digital-to-analog current converter (1) with at least one comparison data word. An analog second comparator (5) compares the voltage drop across the first resistor with at least one reference voltage and applies its output signal to a flip-flop (8). A comparison circuit (11) monitors the magnitude and/or the presence of the output load dependent on the output signals of the first comparator and the flip-flop.

Abstract: A video down conversion system compliant with the Advanced Television Systems Standard (ATSC) includes a decoder which decodes a Main Profile, High Level (MP@HL) image and employs a downconversion processor to produce a standard definition video signal. The system stores a subsampled image in order to reduce memory requirements and employs an upsampling filter to generate reference image data from the stored. subsampled image. The reference image data spatially correspond to the image data produced by the video decoder before it is subsampled. The upsampling filter uses different filter coefficients based on the subsampling phase of the stored image and the half-pixel indicator in the motion vector which is used to locate the downsampled reference image data in the stored subsampled image.

Abstract: A discrete cosine transform domain (DCT) filter for lowpass filtering a high resolution encoded video image represented as frequency-domain coefficient values, such as macroblocks, before decimation of the video image in the spatial domain. The DCT filter masks or weights the DCT coefficients of the video image macroblocks before processing by an inverse DCT. The filter may be implemented as a block mirror filter in the frequency domain, and the filter values may be combined with the IDCT coefficient values. Original motion vectors of the high resolution encoded video image are translated because low resolution reference images used by the decoder are not equivalent to the original high resolution images. Therefore, motion vectors are scaled to retrieve low resolution prediction blocks which are up-sampled to generate the original pixel and half-pixel values in the spatial domain.

Abstract: A circuit checks the value and the existence of an external load of a digital-to-analog current converter. A first comparator compares a digital word to be converted, with a comparison data word. The output signal of the first converter indicates during which periods the digital data word is greater and during which periods it is smaller than the comparison data word. A second comparator compares the voltage at the output of the converter with a reference voltage. The output signal of the second converter indicates during which periods the output voltage is greater and during which periods it is smaller than the reference voltage. A comparison circuit checks the existence and the value of the output load by comparing the time periods indicated by the output signals of the two converters. Thus, a conclusion about the existence and the value of the output load is possible at any time.

Abstract: A technique for speculatively issuing instructions using an out-of-order processor. A cache miss by a load instruction results in either a reissue of all subsequently issued instructions for an integer instruction stream, or a reissue of only truly dependent instructions for a floating point instruction stream. One version of the technique involves issuing and executing a first instruction, and issuing a second instruction during a speculative time window of the first instruction that occurs after the first instruction is issued. The technique further involves executing the issued second instruction when the first instruction is executed in a first manner, and reissuing the second instruction and executing the reissued second instruction when the first instruction is executed in a second manner that is different than the first manner.

Abstract: A method for machining an annular layer or coating of grinding discs of boron nitride or diamonds at the circumference and/or the end face of a disc by means of a tool grinding disc which is especially coated with a silicon carbide layer. The workpiece disc is fed with a first predetermined rate of feed towards the workpiece disc. After the contact of the tool disc with the workpiece disc the tool disc is fed with a reduced rate of feed until a cylindrical or plane surface of the grinding coating of the workpiece disc is achieved. One or a plurality of ultrasonic sensors measure the sound or the vibration generated by the spindle of the workpiece disc. The sound or vibration analyzed in order to automatically reduce the rate of speed if at least one ultrasonic sensor detects contact between the tool disc and the workpiece disc. The grinding process is stopped if at least one of the sensors detects that the workpiece disc is cylindrical or plane, respectively, at least during one revolution term.

Abstract: An apparatus for dispensing beverages including a fluid conduit terminating in a conduit exit, the conduit exit being oriented upwardly when the apparatus is in an operative position, and a dispenser head defining an enclosure surrounding the conduit exit, the dispenser head having a pouring aperture opening onto the enclosure. The pressure within the fluid conduit is regulated so that beverage traveling upwardly toward the conduit exit experiences a stagnation point, causing the beverage to pour from the pouring aperture of the enclosure due to gravity.

Abstract: A transport decoder 110, for receiving and processing a transport data stream using MPEG-2 formats, includes connections to a physical layer channel interface (channel interface) 112, a buffer memory 114, a host microprocessor 116, audio and video decoders 118/120, and clock signal circuitry 122. Upon receipt of a discontinuity indicator, the transport packet headers are parsed and transport packet payloads are stored in memory. Subsequently, upon receipt of a next program counter reference (PCR) value, a counter is loaded with the received program counter reference value. Next, the data stored in memory is searched for a time stamp and, when one is found, the time stamp is retrieved. Finally, a timer interrupt is set for a point in time approximately one frame time before the time stamp value, and, when the timer interrupt occurs, the program counter reference value is sent to the decoders, thereby providing sufficient time for the decoders to process data.

Abstract: A method and apparatus provide for testing the useful vacuum of a dental vacuum system having at least one high volume evacuator valve (HVE) or hose. The vacuum tester is simple, inexpensive, can be used by non-technical personnel, is easily fabricated to test a wide range of performance standards, and evaluates useful vacuum performance during full flow (that is a real-life situation). The tester includes two simple components, an adaptor tube that is placed into contact with an HVE or hose, and a vacuum indicating weight which cooperates with the adaptor tube. With the dental vacuum system operating the weight is brought into position with respect to the tube so that gravity acts to move the weight away from the tube, and then the weight is released. If the weight moves away from the tube the useful vacuum conditions of the dental vacuum system are insufficient, whereas if the weight stays in operative position with respect to the tube the useful vacuum conditions are sufficient.

Abstract: A cathodoluminescent anode is formed on an insulating substrate, while on another insulating substrate are formed cathode conductors, an insulating layer, a grid layer used for the formation of grids, holes in the insulating layer and the grid layer and microtips in the holes. Moreover, a thin insulating layer is formed on the grid layer in order to limit the current liable to flow between the anode and the grids. Another thin layer or film is formed on the thin insulating layer that is sufficiently conductive or resistive to prevent disturbance by the thin electrically insulating layer, of the electric field created between the microtips and the grids.
